In bisection method an average of two independent variables is taken as next approximation to the solution while in false position method a line that passes through two points obtained by pair of dependent and independent variables is found and where it intersects abissica is takent as next approximation..

What is the advantages of secant method?
Advantages of secant method: 1. It converges at faster than a linear rate, so that it is more rapidly convergent than the bisection method. 2. It does not require use of the derivative of the function, something that is not available in a number of applications. 3. It requires only one function evaluation per iteration, as compared with Newton's method which requires two. Disadvantages of secant method: 1. It may not converge. 2. There is no guaranteed error bound for the computed iterates. 3. It is likely to have difficulty if f 0(α) = 0. This means the x-axis is tangent to the graph of y = f (x) at x = α. 4. Newton's method generalizes more easily to new methods for solving simultaneous systems of nonlinear equations.
Use the Bisection, Newton’s, and Secant Methods to find the solution of the equation x - cos x = 0 over the interval[0,pi/2] accurate to within error = 0.005, wherex is in radian. For Newton’s method, try initial guesses including x0 = 1?
Bisection Method: Begin with the interval [0, pi/2]. The midpoint of the interval is x1 = pi/4. Calculate the value of the function at x1: f(x1) = pi/4 - cos(pi/4). Since f(x1) > 0, the solution must be in the interval [0, pi/4]. Now consider the midpoint of this interval, x2 = pi/8. Calculate the value of the function at x2: f(x2) = pi/8 - cos(pi/8). Since f(x2) < 0, the solution must be in the interval [pi/8, pi/4]. Now consider the midpoint of this interval, x3 = 3pi/16. Calculate the value of the function at x3: f(x3) = 3pi/16 - cos(3pi/16). Since f(x3) > 0, the solution must be in the interval [pi/8, 3pi/16]. Continue this process, calculating the midpoint of the interval and the value of the function at the midpoint, until the difference between the lower and upper bounds of the interval is less than or equal to the error of 0.005. Newton’s Method: Try an initial guess of x0 = 1. Calculate the value of the function at x0: f(x0) = 1 - cos(1). Calculate the derivative of the function at x0: f'(x0) = 1 + sin(1). Calculate the next x-value using the Newton’s method formula: x1 = x0 - f(x0)/f'(x0) = 1 - (1 - cos(1))/(1 + sin(1)) = 0.6247. Calculate the value of the function at x1: f(x1) = 0.6247 - cos(0.6247). Calculate the derivative of the function at x1: f'(x1) = 1 + sin(0.6247). Calculate the next x-value using the Newton’s method formula: x2 = x1 - f(x1)/f'(x1) = 0.6247 - (0.6247 - cos(0.6247))/(1 + sin(0.6247)) = 0.739. Continue this process until the difference between two successive x-values is less than or equal to the error of 0.005. Secant Method: Start with two initial x-values, x0 = 0 and x1 = 1. Calculate the value of the function at x0 and x1: f(x0) = 0 - cos(0) = 0, f(x1) = 1 - cos(1). Calculate the next x-value using the Secant method formula: x2 = x1 - f(x1)(x1 - x0)/(f(x1) - f(x0)) = 1 - (1 - cos(1))(1 - 0)/(1 - cos(1) - 0) = 0.6247. Calculate the value of the function at x2: f(x2) = 0.6247 - cos(0.6247). Calculate the next x-value using the Secant method formula: x3 = x2 - f(x2)(x2 - x1)/(f(x2) - f(x1)) = 0.6247 - (0.6247 - cos(0.6247))(0.6247 - 1)/(0.6247 - cos(0.6247) - 1) = 0.7396. Continue this process until the difference between two successive x-values is less than or equal to the error of 0.005.

What is Morse taper and what is Jacobs taper?
The Morse Taper is a method used by machinists to reliably join two rotating machine components. The Jacobs Taper (abbreviated JT) is commonly used to secure drill press chucks to an arbor.
